combine two stacked charts (Excel 2003)

I have two stacked charts each showing two data sets. I'd like to combine them into one chart but I still want two vertical bars with two data sets each (not one vertical stacked bar with four data points). I can't see how to combine these w/o resulting in a single bar graph. Is there a trick or is this not possible?

Data1 80,120
Data2 170,250

So I had two charts with one stacked bar each but can I have two stacked bars with two data points on one chart?
